I noticed that there is a draggable bar at the bottom of the main editing window that, when dragged up, reveals another editing area. However, this area does not appear to be functional - a cursor will appear, but there is no text and key presses are not recognized. Is this a feature that is still in development?

That editing area that you are talking about is the compiler's message dialog window. When you compile a program and it has errors or warnings, those message will appear in that bottom window.

Oh, ok. I never made that connection in the first place. It looks exactly the same as the main editor window and many of the IDEs that I have used utilize a two-pane editing window. And since this software still has a bit of "beta version" feel, I assumed that it was a feature that had not been completely implemented yet.

Also, I use version 1.02 and the about box still says 1.0.

The compiler status area is fully operational.

It is normally hidden in normal use until there are errors in your program that you are compiling.

There is no need to manually resize this bar, as RobotC will automatically resize it to display the errors during compile. If there are no errors, then the status area disappears, as to maximize your type space for the program.
